The invention relates to a heel-piece for a safety ski binding, the heel-piece being released when the load on the binding exceeds a specified limit. A link mechanism is mounted on the heel-piece for connecting the sole-holder to the binding plate of the ski. The link mechanism is engaged by two spindles, which in the operational position of the heel-piece are transverse to the ski and parallel to its surface. The sole-holder is connected by the link mechanism to the binding plate and to the spindles, these components being mutually engaged by a spring-loaded detent/detent-track. In order to achieve compensation for defective settings of the heel-holder, the invention provides that the sole-holder is connected to the binding plate only by the link mechanism. Further, one of the components of the detent/detent-track system is connected with one of the binding plate and the sole-holder and the other component of the detent/detent-track is connected with the other of the binding plate and the sole holder.
